A research team at the Institute of Neuroscience, Center for Excellence in Brain Science and Intelligence Technology, Chinese Academy of Sciences, achieved a technical milestone in non-human primate cloning by generating two genetically identical long-tailed macaque monkeys using somatic cell nuclear transfer. The cloned monkeys were named Zhong Zhong and Hua Hua after the Chinese word "Zhōnghuá," which means "Chinese nation or people." Zhong Zhong was born on Nov. 27, 2017, while Hua Hua was born on Dec. 5, 2017. This work was published as a cover story in the journal Cell on Feb. 8, 2018.
